ROOFING.

SPECIFICATION forming part of Letters Patent No. 645,526, dated March 13, 1900.

Application filed January 8, 1.900. Serial No. 709. (N0 specimens.)

- and fully as lasting, besides being quicker to put on than slates or shingles.

Heretofore all roofs composed ofearthy materials applied in a plastic state have been put on all in one piece or in two large sections without overlapping each other, so that they were apt to crack from the shrinking and swelling of the roof-boards upon which they were applied or from other causes.

the plates or slates of the roofing.

ness corresponding to the upward projection Now the object of this invention is to so apply the roofing-cem ent that when set orhardened it will be composed of small plates held in place by nails and overlapping each other precisely like shingles, each plate or slate being just as separate from all the others as are the slatesor shingles upon a roof of those materials. I attain this object by applying the roofing-cement in the manner illustrated in the accompanying drawings.

Figure 1 is a perspective View of asmall roof partly covered; and Fig. 2 is a plan view of a templet or pattern for forming an ornamental design, if desired.

A represents the naked roof-boards.

B is the portion already covered.

.The process of applying the cement is as follows: Upon the lower edge or eaves of the roof-boards is tacked or lightly nailed a strip of board, projecting just enough above the roof-board to give the desired thickness for The lower roof-boards are next covered with paper of a width of eighteen inches or less; or in lieu of paper any other very thin material may be used. Next a row of nails is driven through the paper into the roof-boards a few inches from the lower edge. These are to be left projecting from the board nearly as far as the proposed thickness of the roofing-cement. Such a row of nails is represented at E in the accompanying drawings. The cement is next plastered on over the paper to a thickof the strip tacked on the eaves and extending up the roof for several inches, but diminishing in thickness, exactly as would a course of shingles. Then while the cement is still soft it is cut with the trowel or other instrument into sections representing shingles. The cement incloses the nails driven into the roofboards, and thus when set the plates are held firmly in place. The same process is then repeated for a double course, the second course being out upso as to break joints with the course beneath. Next a board of the width which it is desired to have the slates or plates show to the weather and of the thickness desired for the butts of the plates is laid with one edge at the lower end of the'course just applied. Alayer of paper is nowlaid'on the part above the board, another row of nails driven, and the cement plastered on and cut up into sections, as before. The board is next moved up its width and the same process repeated until the roof is finished. In the drawings, G is the board, laid in position for putting on the next course, with the paper D and the 'nails E in position.

The cutting in each case should be only through the cement to the paper and not through it.

The object of using the paper is manifestly not to turn water, but to prevent the diffen ent courses from cementing together. Very thin paper is best.

It will be seen that the board used as a guid in forming the butts of the slates can be cut into points, as shown in Fig. 2, or into any other ornamental design desired.

What I claim as my invention, and wish to secure by Letters Patent, is

A roof composing an earthy cement applied in a plastic form in courses, with paper or some similar material between the roof-boards and cement, and between the diiferent courses of cement and the whole held in place by nails driven part of their length into the roofboards, and the rest of their length inclosed in the cement, and each course cut up into sections, or slates, for the purpose and in the manner substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
